What is considered the best method for searching for hot spots?

Gridding is regarded as the best method for searching for hot spots because it provides a structured and systematic approach to identifying any residual heat that may not be visible to the naked eye. This method involves dividing an area into smaller sections (grids) and thoroughly checking each section for signs of heat or smoldering fuels. By doing so, firefighters can ensure they cover the entire area effectively and efficiently, reducing the risk of missed hotspots that could reignite.

This systematic approach allows firefighters to methodically search each grid square, making it easier to keep track of areas that have already been checked, thus providing a thorough examination of the fire-affected zone. In contrast, other methods like following the wind direction, water spraying, or team circling may not provide the same level of detailed scrutiny or systematic coverage that gridding offers, potentially leaving some areas unchecked.
